I have been experiencing the fan running at high rpm and the computer completely slowing down when there is slight pressure applied to the bottom of my macbook pro. I went on Activity Monitor and it shows kernel_task running at over 100% cpu usage. I have already tried resetting PRAM and SMC but those did not work.

My HP CS5200 all-in-one prints fine under Snow Leopard but OS X doesn't "see" the scanner. I need that scanner. I have been meaning to get a Wifi-enabled printer so this appears to be a good opportunity to do so. A few searches for all-in-one printers and Snow Leopard reveals that there are a lot of issues out there. I'm hoping to go out and buy something that works right out of the box today. What models/brands do you guys have working on 10.6 in scan and print mode now?

My computer keeps freezing and applications keep shutting down unexpectantly. So when I went into the activity monitor I saw that Kernal_task and inkjet1 seem to be taking up the most CPU, threads, and memory. What are they? How can I make my computer more efficient? Are these processess causing my computer to be so slow and freezy?

I had my first leopard problem on my 1.67 15" powerbook last night. I lost bluetooth so I restarted, I went to the activity monitor and there was a kernel task eating up 152 mb of my ram. All updates are current and I have 2gb of ram. Any ideas as to what this action is doing. I also have a dual 2.4 g5 with 3.5 gb of ram(but no kernel task issues).

In the memory tab in activity monitor, it shows kernel_task which takes up 440 MB. It takes a huge amount of my memory. Also, my macbook pro is running down. I believe that one of the reason for this is kernel task. How do I fix this?
Is there any specific reason Kernel_Task seems to think he owns the place? What gives? It's like I turn my MacBook on and he's all like "oh hai! Ize just a system task! 50mb of memory? That's cool that's cool" Then only 2 hours later he's all like "Nah man, I just needed some more room see, it's like 120mb ain't dat much, k?"
I know that OS X handles ram real good and all, by freeing memory when it's required for higher-priority tasks, but I also know that it takes a bit more time to clear that memory AND re-allocate it...
So, is this a memory leak? And while I'm at it what about iChat Agent and Colloquy that are battling out to be RAM champ?
OH, and I haz 2gb installed at the moment.
I've been recently realizing that every time i use safari or socialite for a few mins I get a lot of 'beach ball' time. The application would show in red (not responding) in activity monitor and kernel_task would have over 1,900 threads, that will decrease slowly after I force quit the applications.
View 8 Replies View RelatedI was working on my Mac but is coming very slow sometimes so I found the problem is the kernel task.
Lex I already use the Clean My Mac and since the first time I delete a lot of things I don't even remember how many. Should I format my drive?
About the iCleanMemory so the system will clear the RAM by it self or should I do something different or use another program?

I have a 13inch MBP running Mavericks 10.9.4 with a 2.7 GHz i7, 16GB RAM, 500GB HD. I just recently had the machine Factory Reset. The only APP's I've added are PAGES, NUMBERS and KEYNOTE. When I check the ACTIVITY MONITOR it indicates that out of 16GB of RAM MEMORY, 5.51GB is being used. Usually ACTIVITY MONITOR indicates that as much as 9GB RAM is being used. This MBP is 3 years old and I clearly upgraded the RAM from 4GB (I think) to 16GB. Since this MBP used to run with only 4GB of RAM total; it seems to me that the current amount of memory being used, from 5.51GB up to 9GB out of 16GB total RAM is unusually high. In addition, the above numbers were displayed when only Safari and Activity Monitor are running. Is this normal for Mavericks OSX?

Noticed i was uploading at high speed (8MB/s) constantly. So i check activity monitor, and kernel_task is uploading huge amount of data, so far 20+gb this morning...
I'm not getting a massive CPU usage (10-15%).
Tried restarting, just starts up again after a couple of minutes.
When I open Activity Monitor, kernel_task is using approx 240 MB of real memory, and 67 of virtual. All I have open is Safari (and Activity Monitor)Seems like alot of real memory for one process.
View 6 Replies View RelatedA few hours ago, I noticed my MBP start hanging and generally processing very slow. Apps would freeze at random times, and generally a lot of odd behavior.
I checked the activity monitor to see what might be causing this. It turns out, the process "kernel_task" is using almost 100% of my CPU. It has stayed within the 70-100% range, and has yet to go down. I tried many things, including restarting my Mac many times, but it remains the same.
Does anyone know why "kernel_task" is taking up so much of my CPU? Is there a way to somehow "reset" the process to get it back to normal?
P.S. I attached a screenshot of the process in the Activity Monitor. You can view it here:
EDIT: I just want to add that I think the "kernel_task" might have started eating CPU when I stopped a RAR program in the middle of extracting an archive. I'm not 100% sure though that this is when the problem started.
Yes you read that right. Your brand spanking new MBP will use a 32-bit kernel as default.
You can force 64-bit kernel but some of your hardware will not be working.
So all that marketing crap about the benefits of 64-bit etc are all B.S.
I don't want a million threads about how this will not effect the running of 64 bit apps, etc. because it will. Your 64-bit app will run but it will not be able to address more than 4Gb of RAM.
There are also many more advantages to having a 64-bit kernel.
My late 2008 15" MBP 2.8Ghz typically shows a CPU temp above 100 degrees Celsius ~ 216 F when using Handbrake. What is considered a normal operating temperature range? Also Activity Monitor show that Handbrake is using more than 100% of the CPU how is this possible? What does it mean? How can you use more than 100% of the CPU?

The battery on my MBP (2007 2.33 Core 2 Duo) has started to die, just like the three others that came before it. It seems like it's only been a year or so since I got a new battery. Yesterday, I was using it unplugged and the computer shut off when the battery was around 58%. I have never seen a battery shut off that early. The worst I had seen before that was a previous battery that would die around 35%.
A couple questions:
1. Is there something I am doing that is causing my batteries to keep dying so quickly? An Apple Genius told me that keeping the computer plugged in all the time can burn out the battery. I don't really want to bother putting the computer through unnecessary charge cycles to keep up the battery life.
2. Is there any way to recoup some of the lost battery life of my current battery, or is it just dead?
3. In replacing the battery, should I buy another Apple battery from the website, or are there better quality 3rd party MBP batteries?
4. On a side bar, I am thinking about purchasing a new MBP, but I am worried that the battery will have the same problem, and it will be much more of a hassle to fix because everything is internal now. I hate having to hand my computer over to Apple Care for a whole day and be without it.
So I bought a macbook pro 13" about a month ago. I've been running coconut battery tests on it and the battery health is only at 89%. This is super upsetting to me. I went to the apple store and they ran their diagnostic test only to tell me that my battery is within specification, so they wouldn't replace it. The health they calculated was 91%.
What should I do? This seems unfair to me.
Coconut battery stats:
Battery capacity: 5141 mAh
Original battery capacity: 5770 mAh
Battery load cycles: 27
Age of your mac: 4 months
So I just opened Coconut battery, and it is saying that I have 101% battery capacity. How is that even possible? In the other hand, iStat says 100%.
View 11 Replies View RelatedI've had my Macbook Pro for just over 2 years and recently bought one of the 2010 models. I'm about to sell my old one but when I downloaded Coconut Battery, I saw that my battery holds a lot less charge than it did when it was new: Have I been doing something wrong or is it just low because the laptop is 2 years old? If it's something I've been doing, I don't want to make the same mistake with my new one.
View 10 Replies View RelatedI usually keep my mac connected to AC power and probably once a week I try to drain the battery. It only has 28 cycles. I bought it last year on november and today when I removed the ac power, a little while after I realized that the battery health went from 88% to 77%! What can I do? I am doing everything that mac says to keep a healthy battery!

If I use my battery to 98% and I charge it, it shows it as fully charges. My cycle count is 4 and it is the 13'' mbp. It is 2 weeks old. I already calibrated it.

I just bought my macbook pro not long ago. around 2months? And my battery is going down really quick. 1% every 3 mins and I only have firefox on and my backlight is turn off. My brightness is turn on to the middle. I was looking at my friends macbook. Doesn't seem to be going down so quickly.

I bought a new battery for my sisters new used MacBook Pro. The instructions with the new battery was not to charge the new battery until it's was down to 2%. And, how many hours should she expect the battery to last until it needs to be charged? This is with normal web surfing with some streaming. The MacBook Pro is a 2.3 GHz Intel Core 2 Duo with a 15" screen form @ 2008.
View 2 Replies View RelatedI'm having a strange issue with my MBP 1, 1. It's recently picked up a new habit that I find to be rather annoying. When the battery gets down to between 5 and 10%, the laptop will just shut off. No hibernation, no sleep, just a hard shutoff. The battery seems to be in good health; although it does have a high cycle count, I still get around 2 hours of usage out of a charge. I would think that a calibration would solve the problem, but with the hard shutdown, would that even be possible?
View 2 Replies View RelatedSo when I bought this the guy said that Apple installed a new battery on it recently. I believe him because when I downloaded the iStat Pro widget it said only 2 or 3 cycles which is because I calibrated the battery. But I just finished charging and the light is green. But it says the charge is only at 97%. I don't see why it should be like this. Also when it's not plugged in the battery only lasts maybe 3 and half hours from just surfing on the internet. But I thought it was supposed to last like 6?(I'm thinking that since mine is an older model, that could be it.
